In-service Inspection & Testing

Always carry out a full visual inspection of the appliance before
undertaking any tests. Although the microPAT is easy to operate, the HSE
recommend training to correctly carry out a regime of PAT testing.
Training with Quick Test will include guidance on what to look for when
carrying out a formal visual inspection, how to operate a PAT tester and
how often to carry out formal visual inspection and tests on appliances in
different environments.

Please contact Quick Test to arrange your training.

Getting Started

Accessories

The microPAT is supplied with the following accessories:-

 Charger
 Test Lead Set
 Short IEC Lead ( used for testing extension leads )

Charging

The microPAT must only be charged with the supplied charger. It is
supplied partly charged but we suggest you charge your tester for at least
1 hour to boost the charge before using for the first time.

Your MicroPAT tester will perform in excess of 2000 tests per full battery
charge. It can also be used while plugged into the charger.

Battery Indicator

The Battery/Charging indicator will flash green for the
first hour when connected to the charger. This is a fast
charge period. After this the indicator will be a steady
green. To fully charge the microPAT it needs to be
charged for 24 hours. It is ok to leave it connected to
the charger.

If an incorrect charger is connected the indicator will flash red and green.

During testing if the battery is low, the indicator will flash red. When the
battery is too low for the microPAT to operate correctly the indicator will be
steady red and the test will stop.

WARNING

Under no circumstance must mains voltage be

connected to the microPAT

Controls

Results Display

Switched On Indicator

The microPAT is very simple to operate. The only controls
are four buttons used to select the required test.
To operate, simply press and release the appropriate test
button.
The indicator next to the test button will flash amber while
the test is being performed.

The test results are displayed for ten seconds after the test
is completed, the microPAT then shuts down.

When the test is complete the results appear on the results display.
If all the required tests pass, the green PASS indicator will light up.
If any of the required tests are a fail, the corresponding red FAIL indicator
will light up.
Additionally the indicator next to the test button will be green or red.

A new test can be started as soon as the results are being displayed,
there is no need to wait until the microPAT has shut down.

Any appliance switch must be in the ‘on’ position during
testing.
When testing Class 1 or Class 2, the microPAT will attempt
to determine if the appliance is switched on.
If it is unable to detect the appliance is switched on, the
‘Switched on ?’ indicator will flash red. If the appliance is
then switched on within five seconds the test will continue.

However because of the design of some appliances it is not
always possible for the tester to determine if it is switched
on. In this case pressing the corresponding test button will
continue the test immediately.

Tests

The microPAT carries out three different types of test. The actual tests
carried out depend on the equipment connected to the tester.

Earth Continuity

The earth continuity test measures the electrical resistance from the earth
pin of the mains plug to an earthed point on the appliance. This has to
have a very low electrical resistance to provide safe earth protection.

Insulation Resistance

The insulation resistance applies a high voltage ( 500V ) to the live and
neutral connections. This is then used to measure the electrical resistance
of the appliance to earth, or any exposed metal part.
This resistance has to be very high to protect the user.

Insulation Resistance - Surge Protected Extension Leads

The microPAT features an option to perform this test at 250V, this avoids
false fail indications when testing surge suppressed extension leads.

Polarity

This is used for extension leads and IEC leads. It checks that there is
correct connection between the live and neutral conductors through the
lead.

Identifying Class 1 and Class 2

Testing a Class 1 appliance

1. Plug the test lead into the tester

2. Plug your class 1 appliance into the socket on top of the tester

3. Connect the crocodile clip or probe to some exposed metal on the
appliance

4. Press the Class 1 button

If the appliance is not switched on, the ‘ Switched on? ’ indicator will flash
to prompt you to do so. If the appliance is then switched on the tester will
proceed with the test. If it is not possible to switch the appliance on, press
the Class 1 button again to proceed with the test. The Class 1 test button
will flash amber while the test is underway.

When the test is finished, either the green PASS indicator will light up, or
the appropriate red FAIL indicators will light up. The Class 1 button will
also be green or red.

If the Class 1 appliance has no accessible metal part (including fixing
screws), then test as Class 2.

Class 1 appliances use an earth connection as a means
of protection.
Class 2 appliances do not use an earth connection. They
are frequently referred to as ‘double insulated’.
Class 2 appliances display the ‘double box’ symbol.

Testing a Class 2 appliance

1. Plug the test lead into the tester

2. Plug your class 2 appliance into the socket on top of the tester

3. Connect the crocodile clip or probe to any exposed metal on the
appliance

4. Press the Class 2 button

If the appliance is not switched on, the ‘ Switched on? ’ indicator will flash
to prompt you to do so. If the appliance is then switched on the tester will
proceed with the test. If it is not possible to switch the appliance on, press
the Class 2 button again to proceed with the test. The Class 2 test button
will flash amber while the test is underway.

When the test is finished, either the green PASS indicator will light up, or
the appropriate red FAIL indicators will light up. The Class 2 button will
also be green or red.

Testing an Extension Lead

1. Plug the extension lead into the socket on top of the tester

2. Plug the IEC end of the short IEC lead into the IEC socket on the
front of the microPAT

3. Plug the 13A plug end of the short IEC lead into the first socket of
the extension lead

4. Press the Cable button, or Surge Cable button if the extension lead
is surge protected

The Cable or Surge Cable test button will flash amber while the test is
underway.

When the test is finished, either the green PASS indicator will light up, or
the appropriate red FAIL indicators will light up. The test button will also be
green or red.

The test must be repeated for ALL sockets on the extension lead.

If the extension lead has an earth connection, but the reading is high
because the lead is exceptionally long, the green PASS indicator will light
up, however the Earth Continuity FAIL indicator will flash amber. In this
case the extension lead should only be used in exceptional circumstances
where the risks are clearly understood.

10

Testing an IEC Lead

An IEC ( kettle ) lead is tested in exactly the same way as an extension
lead.

1. Plug the 13A plug end of the IEC lead into the socket on top of the
tester

2. Plug the IEC end of the IEC lead into the IEC socket on the front of
the microPAT

3. Press the Cable button

The Cable test button will flash amber while the test is underway.

When the test is finished, either the green PASS indicator will light up, or
the appropriate red FAIL indicators will light up. The test button will also be
green or red.

User Cal Check

In order to ensure that PAT testing equipment operates correctly, the IEE
Code of Practice for In-service Inspection & Testing of Electrical
Equipment states that ‘The accuracy of a test instrument should be

verified and recorded annually or in accordance with the manufacturer’s
instructions.’ The microPAT should be formally calibrated annually. Please

contact Quick Test to arrange calibration.

While formal calibration is required on an annual basis, the IEE
recommend that PAT testing equipment is checked on a regular basis to
confirm correct operation.

The microPAT incorporates a unique feature to perform this.

1. Plug the 13A plug end of the short IEC lead into the socket on top of
the tester

2. Plug the IEC end of the short IEC lead into the IEC socket on the
front of the microPAT

3. Press both the Class 1 and Class 2 buttons simultaneously

The Class 1 and Class 2 buttons will both flash amber and all three FAIL
indicators will flash red, but will turn off as each test passes. If the Cal
check passes the green PASS indicator will light up as well as the Class 1
and Class 2 buttons.

110V and 3-Phase Equipment

110V and 3-Phase equipment is tested in exactly the same way as any
other equipment.

The only additional requirement is the use of appropriate adapters to
connect to the microPAT.
